////The first chunk of code here will use 1 SINGLE Class file, one doGet and onePost
////the GOAL here was to pass the VARIABLE "theOne" via an HttpSession, and it works! 
////(you can SKIP the 1st chunk, it's just here to show you I DO understand how to do it this way

////The 2nd chunk of code GOAL is to be able to use 2 SEPERATE Class files, which I do not understand if it is possible or not, it seems like it should be, but at the same time seems like scope problem...
////  have tried for a couple of hours/searching and do not understand what to do here
////  i do know how to do this same type of thing easily by having Servlet 1 write variable to database, then have
////Servlet 2 retrieve it, just would like to know if possible with Sessions, and what must do
